Does a Toyota Camry 1997 automatic model require a gear oil check? And if yes, how often?

By gear oil check I'm assuming you're referring to the transmission fluid. This type of front wheel drive vehicle will never require you to check gear (differential) oil.





In regards to the transmission, yes it does need to be checked. It should be looked at every 15k miles or so. This is not something you need a mechanic to do, simply pull the transmission dipstick and inspect the fluid. It should be red to dark red in color and feel slippery to the touch. If it's rough to the touch or brown/black in color you have a problem.





In most cases checking the trans fluid will not prevent a problem from occurring. It will only notify you when there is one or about to be one. Servicing the transmission properly is key with any vehicle. Depending on how many miles you have you may want to consider having it serviced now. A typical service will include draining all fluid, purging the system, replacing the filter, and refilling with fluid.





This comes with a disclaimer of course. If you have a high mileage car (120-130k+) purging the system can be dangerous and can actually cause failure. If this is the case ask for the the system to be drained, filter changed, and that it's....no back flush or purging involved. Many mechanics/shops will refuse to service a high mileage transmission or require you to sign a complete release of liability in case of failure. New fluid means new detergent which can break up dirt/debris and clog the fluid passages causing slippage, overheating, etc until complete failure.





Bottom line, if it's not broken don't fix it...check the fluid level, color, and consistency from time to time.





Hope this helps!
